Description:

Vitexicarpin has shown antitumor, cytotoxicity, anti-inflammatory, analgesic and immunoregulatory properties.Vitexicarpin can act as a novel angiogenesis inhibitor, it exerts good antiangiogenic effects by inhibiting vascular-endothelial-growth-factor-(VEGF-) induced endothelial cell proliferation, migration, and capillary-like tube formation on matrigel in a dose-dependent manner. It can significantly reduce vascular inflammation, through inhibition of ROS-NF-κB pathway in vascular endothelial cells.

Vitexicarpin induces apoptosis in human prostate carcinoma PC-3 cells through G2/M phase arrest.   

Vitexicarpin (3', 5-dihydroxy-3, 4', 6, 7-tetramethoxyflavone), a polymethoxyflavone isolated from Viticis Fructus (Vitex rotundifolia Linne fil.), has long been used as an anti-inflammatory herb in traditional Chinese medicine. It has also been reported that Vitexicarpin can inhibit the growth of various cancer cells. However, there is no report elucidating its effect on human prostate carcinoma cells. 

METHODS AND RESULTS:

The aim of the present study was to examine the apoptotic induction activity of Vitexicarpin on PC-3 cells and molecular mechanisms involved. MTT studies showed that Vitexicarpin dose-dependently inhibited growth of PC-3 cells with an IC50~28.8 μM. Hoechst 33258 staining further revealed that Vitexicarpin induced apoptotic cell death. The effect of Vitexicarpin on PC-3 cells apoptosis was tested using prodium iodide (PI)/Annexin V-FITC double staining and flow cytometry. The results indicated that Vitexicarpin induction of apoptotic cell death in PC-3 cells was accompanied by cell cycle arrest in the G2/M phase. Furthermore, our study demonstrated that Vitexicarpin induction of PC-3 cell apoptosis was associated with upregulation of the proapoptotic protein Bax, and downregulation of antiapoptotic protein Bcl-2, release of Cytochrome c from mitochondria and decrease in mitochondrial membrane potential. 

CONCLUSIONS:

Our findings suggested that Vitexicarpin may become a potential leading drug in the therapy of prostate carcinoma.

Tracheospasmolytic activity of viteosin-A and vitexicarpin isolated from vitex trifolia.

METHODS AND RESULTS:

The n-hexane extract that has shown activity in the tracheospasmolytic bioassay was fractionated by solvent extraction and from the major active fraction two compounds were isolated and identified as viteosin-A and Vitexicarpin. These compounds blocked spontaneous contraction of isolated male guinea pig trachea induced by histamine; however only Vitexicarpin was active in a model using sensitized guinea pig trachea stimulated by ovalbumin up to minimum dose of 1.3 x 10(-5) M. 

CONCLUSIONS:

The result suggests that Vitexicarpin is able to block effects of histamine released from sensitized mast cells possibly by stabilizing the mast cells membrane function.
